Abstract: A plasma-shell for use in a gas discharge (plasma) display is formed by coating an organic core including a polymeric core with an aqueous suspension of inorganic particles. The coated core is heated to a temperature sufficient to remove the organic core and form a porous bisque shell of inorganic particles with a hollow center. The shell is submerged in an atmosphere of ionizable gas suitable for a gas discharge PDP device. The gas submerged porous shell is heated to an elevated temperature sufficient to sinter and seal the gas-filled shell. The result is a plasma-shell containing an ionizable gas at a predetermined pressure for use in a gas discharge PDP. The plasma-shell may be of any volumetric shape or geometric configuration. Plasma-shell includes plasma-sphere, plasma-disc, and plasma-dome.
